RING-SPINNING MACHINE.

SPECIFIOATIONforming part of Letters Patent No. 643,436, dated February 13, 1900.

Application filed June 20, 189 8- Serial No. 683,999. (No model.)

To aZZ whom it may concern.-

Be it known that we, EUGENE F. Winner and HENRY OONNACHER, of Manville, county of Providence, State of Rhode Island, have invented an Improvement in Ring-Spinnin g Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

10 In the operation of ring-spinning machines .the yarn between the traveler and the guideeye located above the spindle is bowed out or ballooned to such an extent that the yarn of one spindle is very apt to interfere with the IS yarn of an adjacent spindle unless some means be provided for preventing such engagement. Various devices have been employed for the purpose of preventing such interference of the yarns, and the device in most general use consists of a series of separators or blades inserted between adjacent spindles and preventing by such interposition the engagement of two adjacent yarns.

In United States Patent No. 599,539, dated February 22, 1898, the means for preventing interference of the yarns involves a wide departure from the series of individual separators in common use, the said patent showing and describing a longitudinally-extended 3o guard or curtain located back of the spindles, the curtain being connected at its lower edge with the ring-rail and being so mounted at its upper edge that as the ring-rail rises the slack of the curtain will be taken up to pre- 55 sent at all times a smooth surface against which the yarns whip and are prevented from ballooning to such an extent as to interfere with each other.

Our present invention has forits object the 0 production of novel means for preventing excessive ballooning of the yarn between the traveler and the guide above the spindle, such means being broadly of the type shown in the patent referred to-viz., a longitudinally-ex- 5 tended guard located back of the spindles and having a large superficial area, and our invention obviates certain objectionable features of the apparatus shown and described in the United States patent referred to.

Figure 1 is a transverse sectional view of a ring-spinning machine with one practical in ring-spinning machines.

embodiment of our invention applied thereto, the ring-rail being shown at the bottom of its traverse. Fig. 2 illustrates a difierent form of support for the guard, and Fig. 3 is a modified form of guard to be described.

The frame A, bolster-rail B, supporting the spindles S, the ring-rail R, provided with rings R, the roller-beam A, and the thread-board T, having the usual pigtails may be and are all of usual or well-known construction A guard G extends the length of the ring-rail, and it is hung or suspended from a suitable support above'the ring-rail, and, as shown in Fig. 1, hooked bolts a are secured to and depend from the under side of the thread-board, the upper edge of the guard being hung thereupon. When so snspended, the guard swings back out of the way when the thread-board is raised for dotting, as shown in dotted lines, Fig. 1. The guard is made of some thin light material of sufficient rigidity to retain its shape, which is herein shown in Figs. 1 and 2 as curved transversely or in the direction of its depth, with the convex face or sur face turned toward the ring-rail and spindles.

By the convex form given the guard its acting portion is brought nearer to the ballooning yarn g, which by its. impact against the guard is prevented from bowing out excessively. As the ring-rail rises the rear edge thereof travels up along the face of the guard, pushing the latter back out of the way as the rail ascends. The guard may be 8 made of thin sheet metal, cardboard, indurated fiber, or any other substantiallyinflexible material which will preserve its shape and at the same time be of comparatively light weight. If it is found necessary to ex ert still further retarding influence upon the yarn, the acting surface of the guard maybe roughened, grooved, or otherwise treated, or a secondary surface may be applied to the guardas, for instance, a facing (I of cloth may be attached to it, as shown in Fig. 3. This guard performs the office of the wellknown series of separators in preventing interference of the yarns, but in a new way. Not only this, but with a guard such as herein described it is much easier for the operatives to pull the bobbins off the spindles,

and the guard is very much cleaner than the separators, while it is very inexpensive and simple.

It for any reason it should be undesirable to suspend the guard from the thread'board, as shown in Fig. 1, it maybe suspended from hooked stands a Fig. 2, which are secured to and project from the roller-beam A below the thread-board.

In any event the guard is suspended so that it may freely swing back and forth during the traverse of the ring-rail, the relative movement of the rail causing the greater part of the surface of the guard to be whipped by the yarn, thus equalizing wear on the guard and obviating the formation of smooth spots.

In Fig. 23 the guard G of sheet metal or other suitable thin and substantially inflexible material, is hung from a support (1, substantially directly above the ring-rail, and on the front surface of the guard a facing (35 of roughened material, such as cotton cloth, is suitably secured, as by cement. The ringrail in its ascent acts upon the guard and swings it rearwardly on its supports as a fulcruin.

\Ve have herein shown and described a practical embodiment of our invention; but the construction and arrangement herein shown and described may obviously be varied without departing from the spirit and scope of our invention, for so far as we are aware it is broadly new to provide a ring-spinning machine with a guard consisting of a thin sheet of substantially inflexible material longitudinally extended back of the spindles to receive the impact of the yarn as it bows or balloons between the traveler and the guide above the spindles, such impact of the yarn reducing the amplitude of or preventing excessive ballooning of the yarn.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a ring-spinning machine, the reciprocating ring-rail, a support located above it, and a thin, substantially inflexible guard having a roughened surface, pivotally connected with and suspended from said support and extending continuously therefrom below the ring-rail, said guard being engaged by the latter and swung back by the ring-rail in its ascent, impact of the yarn upon the guard preventing excessive ballooning.

2. In a ring-spinning machine, a series of spindles,a reciprocating ring-rail,and a guard located at LIIG'IGFLI of the spindles andcurved backwardly at its upper and lower edges to present a convex surface to theimpactof the yarn.

In a ring-spinning machine, a series of spindles, and a guard having a roughened surface and extended longitudinally behind the spindle, and curved backwardly at its upper and lower edges to present a convex surface to and to prevent excessive ballooning of the yarn.

4. In a ring-spinning machine, a series of spindles, a reciprocating ring-rail, the threadboard above the latter, and a substantially inflexible guard curved backwardly at its upper and lower edges and mounted back of the spindles and extending continuously between the thread-board and ring-rail and unconnected with the latter, to prevent excessive ballooning of the yarn between the ring-rail and thread-board.

5. In a ring-spinning machine, a reciprocating ring-rail, a support above it, a guard curved backwardly at its upper and lower edges and pivotally suspended from said support and having its convex face behind and adjacent the spindles, the rear edge of the ring-rail in itstraverse engaging and swinging the guard.

6. In a ring-spinning frame, the reciproeating ring-rail, the hinged thread-board, and a guard consisting of a thin sheet of substantially inflexible material suspended therefrom and depending below the rear edge of the ring-rail, the latter in its traverse passing along the front of the guard.

7. In a ring-spinning machine, a guard of thin sheet metal longitudinally extended back of the spindles and curved backwardly at its upper and lower edges, with its convex surface turned outward.

S. In a ring-spinning machine, a verticallyreciprocating ring-rail, means for reciprocating the rail, the front beam, and suitable supports secured thereto, combined with a freelyswinging guard which has its upper and lower edges turned backwardly, substantially as set forth.

In testimony whereof we have signed our names to this specification in the presence of two subscribing witnesses.
